IMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 22,936, dated February 15, 1859.

To all whom it may concern:

Be it known that I, DANIEL GLOW, of Janesville, in the county of Rock and State of Wisconsin, have invented a new and useful Improvement in Harvesting-Ihrenines; and I do hereby declare that the following is a full and `exact description thereof, reference being had to the accompanying drawings, making apart of this specification.

Figure l is a top view ot' my improved harvesting-machine; Fig. 2, a side elevation ofthe same; Fig. 3, a section in the line x x of Fig. 1; Fig. 4, a section in the line g/ y of Fig. 1; and Figs. 5, 6, 7," 8, 9, and l() represent detached portions of said machine.

Similar letters indicate like parts in each of the drawings.

The frame ott y improved harvester is constructed by combining with each other in any suitablemannertheparallellongitudinalbeams l1 t', the parallel longitudinal heamsj 7c, the transverse beam fr, and the ingerbarw. The main portion of the weight of said frame is sup ported by the broad-faced drivingwheel a, which is located between the parallel beams h i, and the opposite side ot' said frame is supported by the wheel a, which is located between the parallel beams j L. The tongue of the machine is jointed to the inner surface of the beam t', and to a limited extent plays freely in a vertical direction in the loop y', which rises from its connection with the finger-bar w. The bearing-rim a ot' the driving-wheel projects iny ward from its supporting-arms cc, and a smaller wheel, b, which is placed on the axle of said d rivingw heel, is also securedlto the wheel-arms e o, and is of such a size as to form a narrow annular space between its periphery and the inner periphery ofthe rim rt. A zigzag groove is formed in the inner periphery of the rim a, and a ditt'erently-proportioned zigzag groove is also formed in the `periphery ot' the wheel b. Opposite the annular space between the outer periphery ofthe inner wheel, b, and the inner periphery ofthe rim tof the driving-wheel a lrecessed bearing-surface is formed for the reception of the bearing-plate fn, which has-a transverse groove formed in it for the reception of theslidingbard, whoseinner end terminates in a cross-head, as shown in Fig. 7. The. arms of the cross-head of the sliding bar d are of such asize that the one pointing rearward will, when the bearing-plate a is in the position shown in Fig. 7, fit accurately and easily into the groove in the periphery ot' the wheel b on the main bearingaxle, and the opposite arm of said sliding bar is of such a size that it tits easily into the groove in the inner periphery of the rim a when the bearing-plate n is moved forward to the utmost limit in the r'ecess that receives it, and the screws which retain the said plate are received into the aperturesp p. (Shown in Fig. 7.) The sliding bar el is made to impart the requisite reciprocating movements to the cutter-bar g through the medium 'of lthe vibrating lever c. 'Ihe after end ofthe lever e may either fit into a notch inwan upwardly-projectin g ledge of the sliding bar d or may pass through an aperture in said ledge. The fulcrum-pivot ofthe lever c may bc secured in any proper manner to the beam '23, and the forward end ot the said lever may be connected by any suitable form ot'joint to theinner end ofthe cutter-bar g.

The zigzag groove in the periphery ot' the wheel b and the groove in the inner periphery of the rim a of the driving-wheel are so proportioned that one ot' said grooves will impart amore rapid reciprocating movement to the sliding bar dthan the other. Consequently any desired degree of speed can be given to the movements of the cutter-bar by properly adjusting the position ot the bearing-plate n in' the recess which receives it.

For the purpose ot' enabling the arms of the sliding bar d to glide smoothly from one plane to another of the zigzag grooves which impart the requisite movements thereto, I combine a spring,f, with the beam t' and with the outer end ot' the lever e, substantially as shown in the drawings; or in place ot' saidspring' any other suitable form of spring may be combined with the finger-bar, and with either the lever@ or with the cutter-bar, in any manner which shall produce the same effect in equalizing the strain upon the arms ot' the sliding bar a and causing the same to glide smoothly over the angles of the zigzag grooves in which they are inserted.

A semicircular plate, u, descending from the,

under side ot' the beam t', is in sufficiently close proximity to the inner surface ofthe driving-wheel a b to prevent any straws or trashy matter frm entering the annular space in said wheel.

The drivers seat mis suspended by jointpins between lthe plates l Z, which are also secured by joint-pins to the outer sides of the rear ends of the frame-beams in such a manner that by shifting the position of bis seat the driver can at any moment throw upward the finger-bar to carry it safely over any obstruction that would be liable to do injury thereto.

I am aware that the main supporting-wheel of a harvesting-machine has been furnished with an outer and an inner parallel series of teeth, and that the bearings ofthe crank-shaft of said machine have been so arranged that the pinion on said shaft could be thrown out of gear with one of said series of teeth and into gear with the other series of teeth, at pleasure, for the purpose of changing the number of the movements ofthe cutter-bar which is combined with the said crank-shaft; but this method of imparting the requisite movements to the cutter-bar of a harvester is expensive, is

constantly liable to get out of order, and is attended with a great degree of friction` In the aforesaid arrangement the teeth of the same pinion are forced to match with an outer and inner series of operating-teeth within the drivlng-wheel, whereas the reciprocating bar n in my machine has an outwardly-projecting tooth or arm, which is specially adapted to work into theoutermost propelling-groove ot' the drivingwheel, and the said reciprocating bar has an inwaadly-projecting tooth or arm, which is specially adapted to work in the innermost propelling-groove of the driving-wheel ot' said machine.

Having thus fully described my improved harvesting-machine, what l claim therein as new, and desire to secure by Letters Pat-ent, 1s-

Oonstructing the main supporting wheel thereof in such a manner as to form therein an outer and an inner zigzag groove; but this I only claim when the said grooves have differently-proportioned reaches and bear such a relation to the T-headed sliding bar n and the other parts of the machine which are connected with said bar and with the cutting apparatus that the number ofthe movements imparted to the cutter-bar can be varied at pleasure by shifting the bearings ofthe said sliding bar n from one position to-another, substantially as herein set forth. g

The above specification of my improvements in harvesting-machines signed and witnessed this 15th day of October, 1858.
